Nope, the photo isn't real. It's a Photoshop special. If it were real it would be really funny instead of just mildly amusing.

The bumper sticker can be real though through the magic of CafePress. I'm not sure why anyone would want it, though it might come in handy for some of those cardinals who have to explain themselves to their liberal parishioners. It might also be a fun prank for some seminarians to pull on their cardinal by putting it on his bumper. (Not that I'm advocating that or anything but the profit from sales at the gigoCorp shop do help towards putting my kids through Catholic school!)
